BEARING-MAIN 1N4321 - Caterpillar

The C13 engines are in-line six cylinder arrangements. The engine has a bore of 130 mm (5.12 inch) and a stroke of 157 mm (6.18 inch). The displacement of the engine is 12.5 L (763 cu in). Each cylinder has two inlet valves and two exhaust valves. The firing sequence of the engine is 1-5-3-6-2-4.The engines have two turbochargers. The engines arrange the two turbochargers in series. The two turbochargers allow the engine to have boost over the entire engine rpm range. The use of two turbochargers increases the maximum boost pressure to 410 kPa (60 psi). The engines also use a precooler before the air-to-air aftercooler (ATAAC).The Electronic Unit Injector (EUI) provides increased control of the timing and increased control of the fuel air mixture. Engine rpm is controlled by adjusting the injection duration. Engine timing is controlled by the precise control of fuel injection timing.The Engine Control Module (ECM) monitors the components of the engine during operation. In the event of a component failure, the operator will be alerted to the condition by the use of a check engine light and an event code will be logged in the ECM. Caterpillar Electronic Technician (ET) can be connected to the engine in order to read any logged faults. Also, the cruise control switches can be used to flash the code on the check engine light. Intermittent faults are logged and stored in memory. Starting The Engine
The engine's ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in 30 seconds, release the starting switch. Allow the starting motor to cool for 2 minutes before the starting motor is used again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
The ECM will set the cold start strategy when the coolant temperature is below 18 °C (64 °F).When the cold start strategy is activated, low idle rpm will be increased to 1000 rpm and the engine's power will be limited.Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 18 °C (64 °F).
The engine has been running for 14 minutes.Cold mode operation varies the fuel injection amount and the timing for white smoke cleanup. The engine operating temperature is usually reached before the walk-around inspection is completed. The engine will idle at the programmed low idle rpm in order to be put in gear.
Do not move the vehicle with the engine in the cold mode condition. Engine power could be noticeably reduced. At a vehicle speed above 8 km/h (5 mph), low idle rpm will be reduced to the customer programmed low idle and the power will still be reduced.
After the cold mode is completed, the engine should be operated at low rpm until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine
